MECHANISM FOR CONVERTING MOTEON.

SPECIFICATION forming part of Letters Patent No. 413,284, dated December 23, 1890.

I Application filed May 28, 1890. Serial No. 352,885. (No model.)

To all whom it may concern.-

Be it known that I, WARREN T. KELLOGG, of the village of Lansingburg, county of Rensselaer, and State of New York, have invented a new and useful Improvement in Mechanism for Oonvertin g Reciprocating Rotary Motion into Continuously Rotating Motion for Forges, Blowers, &c., of which the tation of the pinion was limited to the measure of the pinions circumference on the perimeter of the segment, and to get the required speed a larger geared segment must be used than was convenient to operate. Another method was to attach to the ends of a centrally-pivoted rock-shaft a belt that would engage with a pinion on the clutch-shaft; but by this method when the rock-shaft was down at each end of its traverse there would from necessity be slack in the belt, and the latter at such times did not operate upon the pinion. To improve upon these older methods is the object of my invention, and this I accomplish (as will be more fully detailed hereinafter in connection with its illustration) in applying to a segment that is centrally pivoted and provided with an operating-handle a sprocketchain that is attached at each end to one of the ends of the segment, and therefrom extended downwardly, so as to pass underneath and engage with a sprocket-pinion arranged on the clutch-shaft, and so that in whatever position the segment may be as it is reciprocated the belt will tangent on the segment and be taut, and thus nearly the whole length of the sprocket-belt is adapted for driving purposes and as much so as a segment having a perimetral length equal to the length of the sprocket-belt would have.

Accompanying this specification to form a part of it there are two plates of drawings stirrup sides a 10 as shown at Fig. at.

containing six figures illustrating my invention with the same designation of parts by letter-reference used in all of them.

Of these illustrations, Figure 1 shows in a side elevation my invention applied to operate a blower with the segment shown as nearly at the extreme traverse of its upward throw, and Fig. 2 shows the same parts that are shown in Fig. 1, with the lever down and the segment almost at the end of its downward movement at the front. Fig. 3 shows in side elevation the parts shown at Figs. 1 and 2, but with the opposite side facing the view. Fig. 4 shows a front end view of the mechanism. Fig. 5 shows a section taken on the line as w of Fig. 3, and Fig. 6 shows a section taken through the clutch on the line 00 m of Fig. 4.

The several parts of the mechanism thus illustrated are designated by letter-reference, and the function of the parts is described as follows:

The letter F designates the frame having an arched top A.

The letter U designates a stirrup downwardly projected from the arched top A, so as to be between the frame sides f f The letter S designates a segment made with a shaft S having its bearings in the This segment is provided with a handle-arm H, and as thus arranged is adapted to be reciprocatin gly rotated on its shaftbearings.

The letter m designates a stop to arrest the upthrow of the segment.

The letter P designates sprocket-pinion arranged on the clutch-shaft S said shaft having its bearings in the frame sides f at b b in brackets J, arranged thereon, as shown at Fig. 4.

The letter B designates a sprocket -belt, which at each of its ends E is attached to one of the segment ends c and this belt between Where thus attached is extended downwardly and arranged to be beneath the sprocketpinion P, so as to engage with the latter.

The letter O designates the clutch that is made with the annular ratchet part B, the clutch-disk part d moving therein, the pivoted pawlsp with the annular ratchet attached to the hub of the driving-wheel W, with the clutch-disk (Z attached to the shaft 8", so that when the latter rotated in the direction of the arrow shown at Fig. 6 the pawls p engage with the ratchet to communicate motion to the driving-wheel \V, causing it to turn on the shaft S \Vhen the clutch-disk is reversed, then the pawls pass over the ratchet without engaging therewith, the clutch thus shown and described being an old and well-known device.

The letter B designates a belt arranged to run on the driving-wheel \V and the blowerpinion p to communicate motion to the latter, and I the blower.

As thus constructed and arranged, when the segment is reeiproeatingly rotated by means of the handle while passing downwardly at the front, it. operates the pawl-disk to turn in the direction of the arrow at Fig. 6 and the pawls to engage with the ratchet R to rotate the wheel \V, and when the front end of the segment rises in return then the pawls of the clutch overrun the ratchet without engaging therewith, so that the momentum imparted to the wheel TV by the descent of the front end of the segment continues the rotation until thereversing movement of the segment has been had when the pawls again engage to give fresh impulse to the momentum of the driving-wheel. By using a combined segment and connected sproeket-belt, as thus described, a much greater length of surface engagement is had with the pinion at each reciprocation of the segment than if the latter meshed directly into the pinion, or if a belt was used upon a rock-shaft, which at each oscillation produced from necessity a period of slack in the belt when there was no engagement with the pinion.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination, with a segmentpivoted at the diametrieal center of its circular projection and adapted to be reciprocatingly rotated upon its pivot-shaft, of a sprocket-pinion arranged upon a shaft in vertical alignment with said segment, and a sprocket-belt which at its ends is attached to the opposite ends of the segment and arranged to engage tangentially with the face of said segment when reciprocated, and also to engage with said sprocket-pinion, substantially in the manner as and for the purposes set forth.

2. The combination, with the segment S, constructed to be reeiprocatingly rotated on the shaft 5 and provided with the handlearm ll, of the shaft S, having secured thereto the sprocket-pinion P and the clutch-disk part (Z, the driving-wheel \V, having upon its hub the ratchet R and adapted to turn on said shaft S", and the sprocket-belt I at its ends attached to the opposite ends of said se ment and engaging with said sprocket-pinion, and the belt B arranged to run on the wheel \V and to engage with the pinion 17" on. the blower, substantially in themanner. as shown and described.
